A Problem faced in monitoring worker exposure is that most workers keep moving about on the shop floor as part of their normal duties. The instruments therefore must be worn by the worker and as such the APM 800 system uses a light weight battery operated pump enclosed in a compact aluminium cabinet provided with a clip so that the system can be belt worn.
The APM 800 systems are capable of sampling air at flow rates ranging from 0.5 to 3.0 LPM – the desired sampling rate for most dusts ( silica, asbestos, oxides of lead, calcium, chromium, arsenic, manganese, etc.) and fumes ( lead, copper, iron cadmium, etc.).
The system is designed to operate for a full shift of 8 hours making it easier to compare worker’s dose to the TLV levels specified.
Special features:
- Portable, Light weight and easy to use
- Battery operated pump runs for a full shift of 8 hrs
- Rechargeable Ni – Cd. Battery
- Practically maintenance free
- Sampling rate calibrated against reference setups for reliable results
